onTouchListener for entire screen

Question

I have a screen filled with buttons, but want the onTouch-method to use the entire screen's coordinates. I first tried using a RelativeLayout with an onTouchListener, but never managed to make it "connect" with the listener (i.e. nothing happened when screen was touched), I also tried putting an ImageView on top of the screen, and then making this view invisible.

This last method gave correct responses to onClicks, but I never managed to make it invisible.

If this is the best solution, which I highly doubt, how do I make the ImageView totally invisible, without losing its onTouchListener (I've experimented with white backgroundColor and setAlpha(0)).

Can I somehow make the onTouchListener react to the whole screen, using global coordinates, while the screen is showing (and altering) several buttons (preferably without the invisible imageview)?

If you don't understand what I'm asking for, feel free to complain about that. I'll try to fill the gaps as needed.

Edit:

I've now managed to resolve the issue by using the regular onTouch-method. I ran into several problems making both ACTION_DOWN and ACTION_MOVE activate the buttons, but I finally got it working. For other people reading this: onInterceptTouchEvent could possibly be used (but I never figured out how to get the screen coordinates instead of the view-coordinates).

Answer 1

Sorry if I'm wrong, but I believe I've just had a similar problem. I wanted a title screen that displayed a picture and on the picture words that say "Click to go on" or something similar. I messed around for a bit and found that you can make a layout clickable.

    android:focusable="true" 
    android:id="@+id/titlescreenframe">

is in my xml file for my layout. The background image is simply in the background attribute (I realize you aren't using images)

Anyway, back in my activity

    private FrameLayout fl;
    ...
    fl = (FrameLayout)findViewById(R.id.titlescreenframe);
    fl.setOnClickListener(this);

And then I use a switch statement to handle that and the buttons that are on the next layout. Here if you need it: Using Switch Statement to Handle Button Clicks

Seems this should work with other layouts as well, and I don't have literally any views on my main layout. (unless the layout itself counts as one?)

Ha! Just realized you said you found the solution. Silly timing. I'll post on the off-chance this helps someone, happy coding everyone. :)
